Re: Power Grid Imbalance
As you asking we want to tell you Power grid imbalance compensation caused by both single-phase consumers and two-phase consumers (induction furnaces, welding machines, quartz smelteries). Causes 1- or 2-phase consumers in the grid due to circuit setup (projection welding machines, mains frequency crucible furnaces) Brief, technology-related asymmetrical loads (electric arc furnaces) Effects Countervoltage imbalance too high (> 2 %) Column heating of three-phase current motors With the same active power, the equipment's current loading from a single-phase load is considerably more than from a symmetrical load, meaning that transformers and lines can be loaded with just part of the nominal power. The consequences of grid imbalance include impaired control and regulation equipment, uneven loading of the transformer (losses, noise), uneven motor operation (losses, wear) and reactive power costs. Grid imbalance is an infringement of utility company requirements. |
